Ok, I need to follow up on the HIT post, but hey, "cardio"and aerobics are subjects that can benefit from some repetition.
So, here are a few of my favorite links about the topics that should shed some light on them.
1. Exercise vs Recreation - this one is a great intro for anyone with a cardio addiction.
2. Why NOT Aerobics?
3. Something is not always better than nothing. (comment discussion is excellent here)
4. Top Ten Reasons Not to Run Marathons - this is a must read for the anonymous commenter who thinks aerobics is a great way to improve cholesterol levels.
5. My own post about Cardio
6. HIIT vs Low Intensity training for fat loss..
7. My opinion on Group Exercise
8. HIT for Cardiovascular Fitness (awesome read)
enjoy
